Wow. My expectations weren't crazy high because of the mixed reviews, but Poros was a great place for a business lunch.
We started with the hummus -- it was amazing. I particularly loved the charred bread they served it with. If I could have eaten 10 slices without embarrassing myself I probably would have.
For my meal I had the prix fixe with the horiatiki salad and the fish dujour which was a barramundi. the horiatiki was the only thing I wasn't crazy about. It was sort of a deconstructed salad so it was big chunks of tomato, a HUGE triangular piece of feta, some "spears" of cucumber, etc. If you love the flavors of these things you'll like it but I prefer more of a mixed salad so I get a little of everything in each bite. I do have to say that everything was very fresh however.
As for the fish; it was a skin on barramundi served with a green pepper harissa and a peach farro salad. WOW. the fish was amazing. So light and fresh and charred to perfection. I thought I would be grossed out by the skin on (I'm not a huge fish person) but I loved it. It was so flavorful...almost like a crust. The harissa was an excellent touch without being overpowering. The peach farro salad was such an interesting flavor combination but it really worked well. The meal left me satiated without feeling bloated.
I also have to remark on the service, which was perfect. From the moment we were escorted to our table, our every need was attended to. My iced tea was never even half empty, and our waiter was very knowledgeable and made some great recommendations! (I'm sorry I can't remember his name!) Our plates were promptly cleared when we finished and the timing of the whole meal was perfect.
One other thing -- they had these amazing little raw sugar cubes for the iced tea...to die for! I wish I could get them for my house!
Some other people have complained that it was expensive. The prix fixe menu was the way to go (not sure that they have that for dinner). The "fish market" menu could get expensive quickly, with fish priced by the ounce. Lunch for two came to $46 before tip, and that included an appetizer. Not cheap by any means but not outrageous and definitely worth it in my mind.
Final comment will be on the decor. The restaurant is BEAUTIFUL. Comfortable yet sophisticated. I was totally impressed.
