I'll be at a conference in St. Louis Wed.-Fri. and am looking for suggestions on where to eat. I'm staying at the Roberts Mayfair on Saint Charles and will not have a car. I'm not afraid of public transport if reliable or a not too long cab ride. I'll have time for dinner on my own Wed. and Thurs. night and then lunch Friday before heading to the airport. I'm a Texas native and looking for what's good in St. Louis. I'll eat pretty much anything and would love one nice meal (where a single diner won't feel to put upon) and maybe a local favorite. I've read a lot about Niche and would like any feedback on their food (esp. whether a single diner...don't mind eating earlier in the evening...would be ok there).
