Thank you all for your advice and words of wisdom. Recently returned from trip #4 to Portland and I wish we could just move there already! Patience, young grasshopper... :)
Anyway, here's a brief food recap:
Gotham Building Tavern for dinner: Very much enjoyed, but I still think clarklewis outshines it significantly. The food we had at clarklewis was one of the better meals I can remember, and while GBT was solid, IMHO it wasn't up to cl's levels. I wonder why. I have to say my favorite part of the meal was the gougeres starter. Wow. Both restaurants are about the same noise level but being from NYC that doesn't really bother me as long as I go in expecting that. I also thought the service was much better at clarklewis; not that it was bad at GBT but our server wasn't as...friendly/sharp.
Higgins - bar @ lunch: Excellent as always. Had a pint of the "Greg" which has got to be one of my favorite beers, period, and the gazpacho with seared tuna. Delicious. Husband had a sandwich which was a BLT except that the "B" was in this case pork belly and he raved about it.
Saucebox, happy hour: Good beer, great deals, good eats. I wish we had taken advantage of more happy hours but there will be other visits!
Daily Cafe, lunch: We so need these in NY. Great food, super-reasonable, super-fresh and delicious. My wasabi tuna salad sandwich (I'm sensing a tuna pattern here!) was so fresh and the bread perfectly warm and plump (does anyone know where they get their bread from?)
Pearl Bakery: Great cornbread and banana nut loaf.
Saint Honore: Stopped in for a coffee and a chocolate ganache. Ganache was nice but I don't think I'll be back. It wasn't bad, just not me.
Mio gelato: Another hit. I had almond and husband had rum raisin, a flavor which I normally think is disgusting but I couldn't stop stealing his spoon this time!
Mother's, brunch: Good again, but I think I misordered. I had the Greek frittata which was okay but a little much for me. But I could have eaten pounds of the roast potatoes which came with it.
Portland Farmer's Market on Saturday morning: I.Am.So.Jealous. Your farm market kicks our greenmarket's butt! We got bread and cheese and berries to die for and coffee and made ourselves a picnic.
We also went to this luncheonette that I now can't remember the name of but it was downtown on 2nd or 3rd and not far from Mother's. It was "(something) & (something)"--I want to say something like "Ivo & Lulu" but that's not it.
A great week of great food! Can't wait till next visit (which will hopefully be a stay)!
