I saw this thread some time ago and have been meaning to pay a visit for a while.
I went last night. Restuarant was pretty busy for a Tuesday evening and not just with people in suits.
Service was attentive, friendly and helpful.
I had a 300g Rib eye (CHF 59), hand cut fries (CHF 9), bearnaise sauce (CHF 1.50) and we shared a bottle of Amarone della Valpolicella (CHF 77).
Certainly not a cheap meal but it was a good a steak (nicely marbled, excellently cooked) as I've had here in Switzerland and I have had a few.
Good for a treat or if someone else is picking up the tab!
