I also walked to El Rey near 20th and Chestnut one afternoon. They participated in the gf eat-a-thon, but everything was cheesy, so I wasn't sure if I would truly be able to get anything interesting to eat there. When I went in, I talked to someone who seemed to know what she was talking about. We looked at a menu together and I got some definite possibilities. I haven't eaten there yet, but I might this week. It's an affordable Steven Starr restaurant near a lot of offices, so I expect that they are packed at lunchtime. But, it is in easy walking distance of my office, so that's a plus.
So, two new restaurants that are kind of interesting that are making a point of accommodating the GF crowd. Now I really want to find an Indian Restaurant that I can have confidence in having GF experience.
