I am treating my mom and my aunt to a visit to the Phillips Collection on Sunday to view the Georgia O'Keefe Exhibit. We're looking for a place to have a late lunch/early dinner that day in the Dupont Circle area, preferably close to the Phillips Collection as my aunt is limited in mobility (but we won't need handicapped facilities). Nothing spicy-ethnic, reasonably priced, good selection of food and comfortable seating. Any ideas? Thank you all!
