S & J Gran Cafe

We enjoyed an amazing breakfast and great service!I my first time and I really enjoyed my delicious GreenSplash Bowl with hot cakes. I also had the best Watermelon Aqua Fresca ever in my life!My husband enjoyed Huevos Rancheros, house made tortillas and the best cup of coffee ever. Now that we have found this wonderful spot we will be returning!

I have seen plenty of people from the Diamond Bar group posting about this Cafe named S & J so I had already bookmarked it to try out for later on. Finally during a free morning decided to give this place a try. The server was super friendly and nice. We asked her what are some of people's favorite items and she suggests to get the chilaquiles I got it with chicken and added avocado. Food came out quickly within 10 minutes or so with freshly scrambled eggs, deep fried goodness on this plate. She noticed I started adding Tapatio and gave me some spicy sauce that was perfect for the meal. I also got to try their Zapata Latte Cacahuate which has some crushed peanuts on the bottom. Overall I enjoyed my meal and the friendly service.

Today was my second time here and this review is more for me than anything. I need to remember what I had and what to get next time. The first time I got the Chapin plate for breakfast. It was unusual with a wedge of cheese, some black beans and a fried plantain. Really good. This time I got their Gran burrito. It was dense with meat, potatoes, cheese, and egg and beans but I would not order it again. It's advertised as containing a spicy sauce but there was none inside and it was very dry and overcooked. All the ingredients were overcooked and seemed like leftovers. It also didn't come with a salsa on the side. So reminder to my future self: don't get the burrito; get one of their Oaxacan breakfast plates or maybe try the chilaquiles.

I rarely ever dole out 1 star reviews and I want to do everything that I can to prevent myself in order from doing so, but after ordering take out here and receiving one of the absolute worst bouts of food poisoning in my life (hey, I at least lost 10 lbs), I just had to do it. My brother and I wanted to order some late breakfast/brunch for take out. We got the iced Mexican mocha (honestly tasted a bit too bitter and had a really grainy sandy texture even after mixing it), their standard waffle breakfast meal that comes with 2 eggs (my brother got over medium) and bacon, and their eggs benedict with potatoes. The benedict looked really sus already when we opened the take out container, but since I was hungry and we were already home without any other food, I just dove into eating it. The spinach was wilted, the eggs were room temperature (this was RIGHT after we took the food home and we don't live to far away), and the Hollandaise sauce had a slightly overly ripe sour cream taste to it. The biscuit was already soggy and it was just a chore to eat this so I barely was ble to completely finish eating 1 piece and had to toss away the other. Now if that was the case with this meal, I would have just relented and given this place 2 stars and maybe I just ordered something wrong off of the menu or if it was an off day, but later on that day I started feeling feverish and ill. There was nothing else that I had eaten since the day before and my brother didn't get sick either (he didn't touch the eggs benny). Once it was evening/night, I had the WORST food poisoning of my life, easily one of the top 3 vomiting sessions ever. I just threw up until there was nothing in my system, I was gagging out bile and saliva, throwing up water, Gatorade, Peptol Bismol and literally everything else that was in my system. It winded me pretty badly that I had to take the next day off of work and then the day afterwards too since I was only becoming okay with drinking liquids (yes it was that bad). I don't think I'll even eat eggs benny again after this experience it was that traumataizing and I still can't explain what could have gone wrong that made me so ill, but never again I can say that for sure.

My favorite breakfast spot to come to in diamond bar. I would say that the food is very authentic and full of flavor. My absolute favorite item on the menu is the A La Mexicana burrito. And their red salsa ughhh soo bomb. I get this every time. I substitute beans for bacon and avocado if you love spice get this. A service is always great. Every server is very attentive and they have a team effort here as far as the ambience, it's always very clean, they always have the best music playing, and my favorite is their chalkboard with all the stuff on their menu.

My friend turned me onto this little cafe and I've come back several times. It's small but very efficient and the service has always been good. The food is great taste and texture is great too.

I've been here before with my boyfriend. He said the food was okay. The service was lousy! We were waiting a long time for our water and food. I went with my family for Easter 2024 and the service was worse! My brother in law asked for salsa and my dad had to go up and get it. My mom's veggie omelet had no substance, the egg was thin and flat. My sister's pozole had too much corn. The restaurant smelled like sewer, made everything worse!! I ordered pancakes and they were hard and dry. I had to ask for butter. I needed to use 5 packets just to make the pancakes edible! I needed to rip and tear the pancakes apart, super dry, rubbery and flat. A breakfast place that can't do pancakes is disappointing and unbelievable. Definitely never going back! People were waiting to be sat while we were there. Groups were sat outside the restaurant. They were having trouble flagging down the server. Overall, the food was subpar but the service was awful and terrible!

Im a fan of great breakfast burritos so I've made it a goal to try them all over SoCal. Traditionally in my opinion, the Mexican style breakfast burritos with real tortillas and beans have an edge over most places I've tried. Today I had the gran burrito and it was absolutely awesome. Probably in my top 2 all over socal. It comes with all three meats listed on the menu and crispy potatoes, eggs , cheese and beans. I highly recommend it with their salsa on the side - I preferred the green but both are really great. I can't believe I've never been here before , very friendly staff and great looking menu! Will be back very soon.

Huevos divorced delicious, the waffles are very good too! I recommend this place. I've been here twice and probably will be back. #LOL'ing

Chilaquiles with asadaGreeted at the door immediately with a non intimidating smile. Seeing the real Latinos serving the Mexican food. The location has plenty of parking in the plaza and the seats vary from a comfortable table for one or a an accommodation of maybe 10 people, if some tables are meshed together. Ordered the asada chilaquiles Plate. Came to the table quickly and was well served; simple, no beans or rice but it is enough! They are crunchy but enough sauce for every bite the asada is thin and tender with freshly shaved cotija cheese, not the powdery bought stuff. with thinly diced white onion to give a little pop of zing, cilantro scattered all thru the top and a complete drizzle of sour cream not a spoonful on one spot . So that every bit has a bit of everything. Looks like a plate you would be served at a fancy restaurant. From start to finish, which was approx 20 mins the chilaquiles were crunchy at edges and smooth and juicy in the center. Did not disappoint!!! The best so far! Just like my tias! Don't tell my Tia....oh and get the cafe de Olla it's one of the best I've had!P.S. if you're into the spicy secret stuff ask for the spicy salsa that only the real ones will appreciate . Next time I might ask for the chilaquiles to be cooked in that red sauce! The atmosphere was pleasant and super friendly. It feels like you're eating at your tias house for a Saturday breakfast.
