My wife and I had dinner at the new Walnut Grill last night.  I usually wait a couple months until the bugs are worked out of any new restaurant, but my friends said the food was great and to give it a try.  We weren't disappointed. The the balsamic and wild mushroom chicken dishes were fantastic.  The table service was excellent.  The only snag was waiting a short time on a reservation.  Again, we eat out regularly and have experienced nightmares going to new restaurants.  This was a minor issue for us since they were extremely busy.  I gave them 5 stars based on what they accomplished in a short period of time.  The food and table service are worth the wait, but make make reservations on weekends to avoid longer waits.
