Having lived in Boston and being a tech bro, I have had sooo much chowder at Yankee Pier in Terminal 3. I don't care if it wasn't really that good, i just drowned it in Da Bomb Beyond Insanity that once nearly got me arrested at the airport
that said, SFO really sucks because the runways are too close, so half the time they have to close one of them due to rain or fog or the like. gotta go at least business class so you get some drinks waiting on the tarmac hoping you're next to someone attractive and / or interesting
i had a good experience at Amsterdam Schiphol - but maybe that was because i was connecting on Alitalia to Milan which was awful minus the fact that i was in the middle of Milan with a gal that was... well i was punching above my weight
also - i thought Milwaukee was quite alright. IIRC it had a flight museum and a really cool used bookstore where i got a rare Henry Miller book. it likely changed since, but Milwaukee seems like one of those mid-major cities (think also Chattanooga and Boise) poised to push Seattle and Denver into the excluded middle (not as cool as NYC or SF but too expensive). Salt Lake City is an interesting one in that regard
speaking of, DIA was built for the future. things are starting to fill out. whether Federico Peña is still cashing fat checks, well, what would i do when i get there. and Blucifer is dope, and we all hope the Illuminati is down there
Atlanta blows Bill & Ted's era chunks, but i think that's more because I-75 makes me want to go full Waingro on the entire SEC
