We stopped by Soda Pop’s last night to find the owners in furious prep mode for an opening today. They were cutting M&M; covered brownies and preparing tuna fish just a few steps from Beverly Center and across from Roger Room. Soda Pop’s, which we first glimpsed on Blackburn + Sweetzer, is a small deli dedicated to a short selection of gourmet sandwiches, sweets, and bottled soda. With bright white walls, a few vintage posters, and a nook of two-top tables, the approach is certainly casual. In a neighborhood of inflated chains and pricey dining options, this looks to be a quick and inexpensive lunch. Soda Pop’s opens today from 11 a.m.-5 p.m. 349 La Cienega Blvd. West Hollywood.
