Well, if Frank is OK with Mexican food (which really is the easiest food to find downtown that won't require taking out second mortgage just to pay the bill), then I suggest El Parian since King Taco does qualify as a chain (although it's not like an Olive Garden or other garbage like that). Plus the restaurant is only a mile and a half from the Wilshire Grand.
Now, as far as meeting up with everyone, I suggest that one of us with a car should pick up Frank and everyone else rendezvous at the restaurant. Parking in downtown LA sucks mightily and is likely to cost more than the food, so it doesn't make sense for everyone to stop at a hotel, pay for parking, and only stay for a short while before moving on.
Thoughts? Alternatives? Death threats?
