I went here several months ago and haven't been back yet, but I've thought of going back many times.
I went with a friend for lunch and we both ordered something vegetarian -- I don't remember what. What both of us remember about the meal is that we were not really impressed. Whatever we had just wasn't memorable.
The dessert was another story. We got a slice of the namesake red velvet cake, and a slice of another kind of cake, which might have been a carrot cake. We both remember the cake being moist and enjoyable, definitely the highlight of the meal.
We also remember the waitress being inattentive to us, (but flirting with another waiter), and the service was a little slow.
If I go back to the Red Velvet Cafe sometime, it will most likely be just for the cake, although I might also be willing to give the lunch menu another try.
