Just about all the DD table service restaurants are going to be a bit on the expensive side, with places like Fulton's being top tier pricewise.
But if you haven't tried Wolfgang Puck's Express, you'll be pleasantly surprised, I'll wager. The prices are decent, for starters, and even though you order "off the wall," your food is brought to your table, and it is eons past typical counter service fare.
Still, while it's more expensive than WP's, I have to keep pushing Raglan Road. It's just a true favorite of ours.
