Tonja McDonald, left, and Emily Ruckel wait on customers at TC Coffee Co., 503 E. Market St. in Celina. McDonald opened the new coffee shop and eatery a few weeks ago. Patrons can sit at family style wooden tables with big sturdy chairs, on couches or at pub-style tables while they enjoy beverages, sandwiches, salads and other treats. It's in a house that used to house the former Assist-2-Sell office.
