I visited Ben's Deli in Boca Raton, FL and ate with all of the old Jewish retirees.
A bowl of pickles and coleslaw were automatically brought out as an appetizer. I normally prefer dill or garlic pickles, but those half sour pickles (light green) were really good. No complaints about the coleslaw either.
I ordered a turkey sandwich and a spinach knish. The knish was good, filled with spinach and potato in a thin flaky crust. It was nice and moist so it didn't need any mustard.
I didn't find the turkey sandwich very impressive. It was overpriced ($9) and came with nothing. It was just a whole lot of turkey between two slices of rye bread. The bread wasn't that great either. I ended up putting some mustard and some of the coleslaw on the sandwich to make it a bit less boring.
Overall, I wasn't too impressed with Ben's Deli. I could think of several other places that have better sandwiches for half the price. Perhaps Ben's justifies the high price by serving Kosher meat, but I don't follow any dietary restrictions based on what's written in an ancient text, so whether it's Kosher or not doesn't matter to me. The sandwich was pretty typical of what these New York Style Kosher Delis serve, so I guess I can't complain too much. Compared to other Kosher Delis though, I've been to much better.
