4 Best Burger Restaurants in Castro Valley

“When I get the urge for a burger, I think Nation's! I prefer this location because the sandwiches are always well put together. Generous amounts of FRESH lettuce leaves,
several large tomato slices ( look like beefsteak variety) and onions- sometimes too much :-)- I just remove the excess. Fresh bun, tasty burger meat... The fries USED to be some of the best- they aren't so special anymore. I saw them fries being lifted from the cooker, but they were not that yummy. I will pass on the fries next time.
The staff is always pleasant. The counter and restaurant is clean... The only drawback is sometimes there are homeless loitering (not so much lately)... I usually order online and pick on schedule.“

“my sunnyside burger was very good next time im going to ask for the fried egg to be cooked a little bit more but my meal was filling...thanx u!!!“

“The CV location is back on track with new staff and it appears things are back on track compared to the end of last year. Pleased to put this location back in the Favs.“

“We have been twice fist just my husband and I. The next day there was 6 of us. Food is good does lack a little flavor. When it says with sour cream it is less then a tsp. Constantly having to ask for coffee refills, and for breakfast I feel quick refills are a must. Food did come out really quick and hot, despite how busy it was. Patio seating was more like musical chairs as everyone kept moving tables due to the sun being in your face and umbrella coverage not great. Overall I would recommend this place, but they definitely have room for improvement. None of the staff looked happy or smiled. I didn't drink but the cocktails were nice looking and they did enjoy them.“
