Hi! Is Lake Chalet able to accommodate large groups of around 15-17 people as walk ins for your outdoor seating mid-week. I saw that reservations are only for indoor seating but wasn't sure if I could bring in 15 people for a Wednesday lunch?

They are able as long as staffing and seat availability are adequate.

True even with the heat lamps it's not recommended that you'd want an outside seating 15 people would not be comfortable freezing to death let alone they might not even have the staff to send a waitress out there

There is room that holds around 28 people. It's been very cold and don't recommend the outside seating. Wednesdays they should be able to accommodate but then there is no guarantee.
