This Migros is bigger than most other Migros in Basel. Especially, food court area including breads, pastries, cakes/desserts and sandwiches, pizza. If you like quiche, try one here. Cheese (Kasse) one is simple but good!! It's very cheap (only 2.60 CHF for 1/4 6 inch). All slices of cakes are very reasonable too (only 2.50-3.50 CHF) and they are quite good. They also sell donut (fluffy donut-hole looking donut).
I think this is one exceptionally cheap and good place to eat.
PS: Try to avoid 11:30-12:30pm. It gets very crowded. read more
