When I used to work on Ocean Park near 28th, I would often have lunch at the very comfortable and very dive-y place called Ocean Park Cafe. It was homey and had Mexican-inspired breakfast foods that I liked, as well as a good selection of veggie options.
That place has been gone for about 8 months, but since I no longer work over there, I haven't had time to check out the place that opened in that spot which is called OP Cafe. I went today for the 1st time. The physical space has been spruced up a bit and is bright and cheery. The food, however, seemed really pretty unexciting and basic. The menu contains eggs in numerous incarnations and a small selection of wraps and salads. Today they had one special: a barbeque tofu sandwich - which is what I ordered. The french fries were nice, crisp and seasoned well; the sandwich was grilled tofu and crispy fried onions bathed in a very sweet BBQ sauce. Eh... maybe the egg dishes are better?
I believe OP Cafe is open until 3pm. It is located on Ocean Park at 31st.
