I had tried to get Isle's vegan scone earlier, but they had sold out by the time I arrived. So I went back the next day and got a hot, fresh scone filled with some fruits (peach and fig? I'm not sure what they were). It was delicious and super-filling, so don't expect to eat anything else for a couple of hours. Best of all, it's super cheap at only $2.
Their hand-squeezed orange juice is also spectacular. It's some of the best orange juice I've ever had in the US---it reminded me of when I was in Brazil and you'd get fresh orange juice at roadside stands next to groves.
There's some seating outside, but it gets filled quickly on the weekends. Inside has a few spots, but it's awfully tight. This place might be a good take-out joint; get some stuff, walk to Lake of Isles or Lake Calhoun and just sit and enjoy some scenery along with a vegan scone and orange juice or tea/coffee.
