Anniversary dinner in Houston

I am making last minute plans for an anniversary staycation next weekend and I am trying to decide where to make a dinner reservation:

BCN
MF Sushi
Da Marco
Theodore Rex
The Pass

We love Brennan's and Tiny Boxwood's (hard to beat the ambiance), but maybe would like to try somewhere new. I prefer classic to New American, but the hype of Theodore Rex makes me want to consider it and the tasting menu at The Pass seems like a classic for this town. It looks like it might be tough to get a reservation at BCN, but it looks like the most beautiful, romantic restaurant! I would like somewhere with a romantic, not stuffy ambiance. I had a great experience at the chef's table at Steak 48, but my husband is not crazy about steakhouses.

Any suggestions? It's our 5 year anniversary so I would like to make it special!
