Sorry I was away when you posted this. Glad you found somewhere. In case you go again, here are some other thoughts...
You can't go wrong for dinner in Birmingham. If you head to any of the following areas you'll find a selection of nice places to eat:
Colmore Row, Temple Row, Newhall Street area
St Paul's Square area
Mailbox
We really like Bank - it's not that bad, but I understand why it attracts the comments above. Parking right next door, and several places to go for a drink nearby. The Prix Fixe menu is a bargain for the quality of food, although only an option if before 7pm.
Bar Estilo (opposite Strada in Mailbox) used to be our favourite, but it fell out of favour with me when the steak went up £2 following a refurb!! Parking on-site with what used to be a good valet, but the bars are rubbish nearby.
Shogun (Japanese) in Mailbox is good for similar reasons.
Only one good place for eating early in Bimingham. Go to Cafe Gusto (also Mailbox) for breakfast. Niiiice.
