Best place for any baked goods including baguettes are from Red Hen Bakery in Bucktown / Wicker Park and on Division in Lincoln Park. They are also at the Lincoln Park Farmers Market on Saturdays in the summer. I love the cinnamon scones too.
I'm a Red Hen detractor esp. the baguettes. They've never done it for me despite the raves. I do however enjoy Bennison's mentioned at the top. Unfortunately, I've found them hard to come by in the city outside of a limited presence at the farmer's markets(which are about done with anyway).
Like I said above, Bennison's baguettes are available at Pastoral on Broadway. They take delivery of a par-baked product from the bakery each day and finish them off in the shop.
Anyway, I'm with you on Red Hen's baguette.
It's an entirely underwhelming product.
