We've always been very pleased with the food offerings at the BWI concierge lounge. We were there 7/7-17:
Breakfast: bread for toast, bagels, cream cheese, pastries, muffins, cereal, milk, juice, etc.
Midday Snack: hummus, cream cheese and chive dip, breads, fish, M&Ms, small peanut butter and jelly sandwiches, mixed nuts, lemonade, iced tea, soft drinks and bottled water (fewer people are in the lounge during the day, so they don't go all out)
Teas and Sweets: delicious tea sandwiches and mini-pastries
Wine and Cheese: several varieties of wine, a great assortment of cheeses, fruit, crudite platter and dip, crackers, hot appetizer, soft drinks, etc.
Desserts and Cordials: huge variety of cordials (Godiva, Amaretto, Bailey's, etc.), delicious desserts (tiramisu, fruit tarts), chocolate covered strawberries
The food is constantly being refreshed by the AWESOME CMs and is very plentiful.
The concierge service and itinerary planning are second to none. The food is just an added (delicious) bonus.
