Mountain Sun Pub & Brewery

Nutrition Facts & Calorie Information

1535 Pearl St, Boulder, CO 80302

59items analyzed
"This menu skews toward bulking — many burgers, quesadillas and burritos are calorie‑dense (often 700–850 kcal) with high fat, though there are a few lighter options. For cutting, choose the Garden Salad (about 150 kcal) or the Tomato Bisque (110–130 kcal) and ask for dressing on the side and to skip cheese or heavy sauces. For bulking, go with the Bison Burger or Speakeasy Steak (around 850 kcal) for lots of calories and protein. Simple swaps (fries → salad, cheese/sauce off) can shift most plates toward a lighter option."
