We were in Grindelwald four nights and ate here twice. That's how much we liked Onkel Tom's. The food is great (thin crust pizza with fresh ingredients), the owners are very friendly (even gave us advice on which trails to take on different days) and the atmosphere is homey and welcoming. If you're not sure which Swiss wine you'd like to try let them pick for you. Eat inside or outside. You won't be disappointed.
