We did two B&C events this year -- Bubble House Friday evening and Lacroix on Sunday at noon. Bubble House was good food, but lousy service. The price was higher than their usual menu ($40 for 3 courses). The apps were quite good -- clam and spinach soup, a pepper and kimchee salad, and Korean dumplings. The entrees we tried were an outstanding whole snapper marinated in red pepper sauce, and beef skewers with onions, mushrooms, and a very hot green pepper, served with sides of cucumber and cabbage kimchee. Dessert was an excellent poached Asian pear.
Lacroix was outstanding in all aspects. The guest chef (Peter Reinhart) had little influence on the menu -- I think it was just the selection of foccaccia. Everying else was Lacroix, and it was great. This is certainly a great big-deal, big-event option ($65 for more outstanding food than any one person could ever eat). There is an appetizer table, a raw bar table, soup brought from the kitchen, a dessert table, and you are escorted into the kitchen for hot food choices (over a dozen) served to you by the chefs (some from hot chafing dishes, such as stews, cassoulet, etc.).
All in all, we got a heck of a lot more for $65 at Lacroix than we did for $40 at Bubble House. Although I might consider going back to Bubble House if White Dog is full and we have a reason to be at 34th and Sansom (the regular menu is much cheaper).
