Even though chains such as Starbucks have made an appearance in Whitehorse [1], go beyond what you know and search out Midnight Sun Coffee Roaster (9002 Quartz Rd., 867/668-7559, Mon.–Sat. 8 a.m.–5 p.m.), with coffee that is as good as you’ll find anywhere. It comes with locally inspired monikers like Sam McGee’s Black.
Also well worth a visit is The Chocolate Claim (305 Strickland St., 867/667-2202, Mon.–Fri. 7:30 a.m.–6 p.m., Sat 8:30 a.m.–6 p.m., lunches $6.50–9), an arty space with handmade chocolates, freshly baked sunflower bread, sandwiches, savory soups, and cappuccino.
In a two-story log building just off 4th Avenue on the north side of downtown, 
Alpine Bakery (411 Alexander St., 867/668-6871, Mon.–Sat. 8 a.m.–6 p.m.) bakes wholesome European-style breads with organic ingredients, but they aren’t cheap. A specialty is Expedition Bread, which stays edible for up to a month. The bakery is also part deli.
Lil’s Place (209 Main St., 867/668-3545, daily 7 a.m.–9 p.m., $5.50–12) is set up as a 1950s diner complete with vinyl booths, a jukebox, gumball machines, and a menu of burgers and shakes.
