Had a few days this week to go sample many of the booths - crowds and lines weren't too bad, but some inconsistency. Some overall thoughts:
Highlights
Fleur de Lys: the duck confit with tomato, olive and polenta was (unexpectedly) my favorite of the event - comfort food that didn't seem heavy and everything worked together
Honey Bee-stro: everything - the roasted cauliflower and the tandoori chicken flatbread were both very good, and the honey-mascarpone cheesecake was the best dessert I had (not quite as good as the boursin maple cheesecake from F&W, but more elements and all done well)
The Citrus Blossom: the tuna tataki was a close second to the duck in France - lots of complex flavors with this one, beautiful presentation and the spicy yuzu glaze was actually spicy - also, a "fun food" in trying to figure out how you're supposed to eat it
Middle of the Road
Flavor-full Kitchen: the roasted beet salad was a nice presentation (and the bed of lemon oil dressing and fried quinoa was tasty), but some inconsistency there on multiple orders over different days. Staff didn't seem to have it all together.
Northern Bloom: both the scallops and grilled maple pound cake were okay, but both were heavy and had dominating flavors - the scallops were overpowered by the bacon and vinaigrette while the green beans were just too oily; for the dessert, the pound cake was really dry and the peach compote wasn't much more than peach slices, but the sweet corn gelato was excellent
Hanami: the frushi was a light dessert option, but overpriced for three small pieces (one of mine was falling apart at that); the soba noodle salad needed more wasabi dressing, less raw vegetables and much better tuna (the tuna tataki at Citrus Blossom was worlds ahead in quality and flavor)
Bauernmarkt: the pretzel bread with ham and gruyere was very good but overpriced - a small pretzel roll with a sliver of ham and a few shreds of cheese on top wasn't a great value at $5.25 (and the most expensive item there at that)
La Isla Fresca: the tropical mousse cake was light and had great tropical flavor (probably perfect for a hot day) - but there are better desserts to be found
Lowlights
Lotus House: I always want to like the China options, and I'm almost always disappointed. This time it was the spicy szechuan beef - a simple dish gone wrong in that it wasn't spicy, the beef was mostly fat and the rice was undercooked to the point of being nearly raw and crunchy
Primavera Kitchen: Italy continues the trend of selling basic dishes of mediocre quality at premium prices (the cheapest item is $7 and most are $8-9). I got the fried green tomatoes with mozzarella ($8) - hoping for an interesting twist on a caprese salad. I was sorely disappointed - two small pieces of mozarella paired with two oversized pucks of simply battered and fried green tomatoes and drowning in balsamic so that the taste was really just "fried vinegar"
Taste of Marrakesh: while the harissa chicken wasn't "bad" it also wasn't particularly good - which for $7 puts it here rather than in the middle of the road (say in the $5 range). The chicken was bland and the dried fruit couscous salad, as near as I could tell, was mostly seasoned with green pepper and chickpeas (there may have been a raisin or two in there).
Drinks: I tried several, but no stand-outs and there are so many choices I usually don't find specific recommendations all that helpful.
