My sister is coming to town all too briefly for a visit- and wants to squeeze in a business-related coffee with possible food on Saturday (tomorrow!)- her host wanted to go to Brasserie Joe downtown- but that's too far/too much of a hassle on this schedule. Plus I live in Waltham, which is so much more convenient! Who can recommend somewhere that will feel like it's similarly upscale (never been to Brasserie Joe but I'm guessing it's a little fancier than our favorite diners)-- for a coffee and possible lunch? I only know the dinner places around here that are fancy and don't know who serves weekend lunch or coffee. Do any of the hotels have an appropriate restaurant/cafe for example?
