I live in StC so we get to the Trailhead about 2-3 times a year. The dinners are okay, the burgers are very good, but the battered fish and appetizers are especially good-esp the barbecue chicken pizza (bbq sauce, chicken breast, red onions and cheese on thinnish crust-awesome, esp with beer!). And the portions sizes are filling for the price. I only drink the blonde ale, which is very good (like BudLight/Select only more robust), so I can't tell you about their other beers. The service is sometimes slow...but that's not necessarily unique to the Trailhead-ALL the restaurants in old StC are slow. Some more than others. I would rate the Trailhead's service as above average on slowness and quality compared to the other restaurants in its class in the area. It seems the restaurants in old StC either want you to have a dining experience or they don't employ enough wait staff. So keep time in mind when you visit any restaurant in old StC. The Trailhead gets unbelievably crowded on the weekends so definitely make a reservation, if they let you. Not really a place for kids, particularly on weekends, as the crowd gets rowdy and it's more of a bar scene. So if you want to take the kids, go on a week night (but NOT on a game night). Never sat outdoors but heard it was nice. After dinner, take a leisurely stroll down Main Street-lots of cute shops for you to peek in the windows at. And many bars, if you're in the mood. There is parking but it fills up fast...across the street and a nearby public parking area. The Trailhead may not be on top of the list of microbreweries in the nation but it's top of the list in St. Louis!
Pros: Fun place to begin the night, aptz awesome, makes a great happy hour and game night hang out
Cons: prices a little high-but not at happy hour, service on slow side, groups over 6 or 8 people (depending how thin you are) plan to sit outside or at two tables
