I'm disappointed to say that I was not impressed by Rocky's Charcoal's Grill, the latest restaurant to take the space on West Estudillo and Haste, next to the San Leandro History Museum. The burgers we had there were OK, but pedestrian - and the chose your own condiments and toppings (sans tomatoes, which you have to ask for separately) was not a winner in my book. If I knew how to properly dress a burger, I'd make it myself :) The patties themselves were on the dry side, and they had only a slight charcoal flavor, though they are cooked on a charcoal grill.
On the plus side, Rocky's only uses fresh beef not treated with artificial hormones and given an all-vegetarian diet. I'd like to see more restaurants do that. The prices are quite affordable, with 1/3 lb burgers starting at $4.25.
I'm sad to not be able to give Rocky's a good review. The people working there were very nice, and I do hope the business to succeed. I should also note, that other people have raved about the place, so I'd recommend you go and judge for yourself.
