Re:Downtown dining Houston, TX
Downtown still rolls up at 5. You are in the area of the high-end, cookie-cutter steakhouse - appealing to the convention, expense-account crowd. My pick of that litter is Vic and Anthony's, which is a few blocks away. I am not big on Tex-Mex, but a friend swears by Ninfa's, a small, local chain - and there is one in the downtown area. A few blocks north of Minute Maid Park is the downtown location of Hubcap Grill. I had a very good burger at their other location north of town.
Should you have a friend with a car, or venture to use a taxi, just on the other side of US-59 is the heavily populated Vietnamese area. I have been to a few good places there with some locals. I wish I could remember their names, but the area is so saturated with good Vietnamese food, the lousy places tend not to last too long. I would bet you could get a good recommendation from the hotel (one of the employees...not the concierge, FWIW).
