Chiming in a bit late, but I went to BLT Steak for the first time on Valentine's day. Despite it being a traditionally "bad" day to go out for dinner, we thought it was excellent - both the food and service. We will absolutely go back.
Haven't been to Wolfgang's but have been to BLT twice. Its excellent. You won't go wrong if you decide to go there but if its better or worse than Wolfgang, can't offer an opinion.
