Coming to St Louis for 3 full days end of May with husband and 3yr old and want to get the most out of it. Planning to visit city museum, zoo, grants farm. Any other must do's? Looking for best local burger, micro-brewery (not sure about that with toddler?), breakfast, and any other local favorite must have foods. We're staying in a condo somewhat close to the arch but don't mind a drive. On previous trip (pre-baby) we have done the arch, river tour, botanical garden, science center, zoo, union station, Budweiser tour. Had Pappy's, Crown Candy, Ruth's Chris, Schlafly (didn't actually eat there); all great.
