Terminal E is really quiet in the morning, doesn't surprise me that there were few options open. Like your SFO experience, if you were at the terminal that late at night, it would have been just as busy.
There most definitely is a dunks post security in E... though given it's at Gate E1A, *just barely so.* You may as well go through to terminal C for your coffee, especially given that dunks limited afternoon hours and the food options in C if you have the time. In general, I agree that E doesn't have enough in the way of dining options - as far as I'm aware, there's only 3, maybe 4 sit down places - but only 1/2 quick serve, and there should be more. Airports are a place where a fast food joint can be really appropriate, but they're not exactly the vibe airports want to have now. (In fact, in certain airports if you know where to look you can still find the shadow of the McD arches surrounded by iPad dining) It's one of the things I'm most looking forward to about the new Terminal is that expansive open hall area which looks ripe for retail and dining.
Logan's site says it's closed on Saturday and Sunday. It's down the escalator too, around the bend, and after the part-time checkpoint; you really have to know it's there. Hawaiian is usually at E11, and of the morning flights departing from upper E gates only BA and Porter are daily; Copa and Hawaiian aren't. I have a hard time seeing there being a lot of unmet morning demand in E.
Interesting. I think Hawaiian is every other day. (That's kind of what I remember when booking tickets.) Porter is certainly daily. I still think that having only ONE "noticeable" quick-serve location for coffee at 8:30am in the morning is very weak for a large international airport. I guess the Dunkins in Terminal E is taking a cue from those speakeasies in East Boston that are hard to find, and you need a secret code to access them.
