I haven't been there since 2004 but Portobello is wonderful! Last trip I had the most devine beef filet for dinner and a most sinful piece of chocolate cake for dessert. Can't wait to go again, which is happening 9/26. It's a little pricey if you're paying OOP, but worth every penny.
We went to Portobello in July 2005 it was our first time and we really enjoyed it. The food was very good, great desserts and the roasted garlic served along with the bread was outstanding. We would definitely go back.
I ate there last summer after La Nouba and had a fantastic meal. It was the tuna wrapped in something and it came with a lobster tail. Yummmy. Nice glass of sangria,appetizer and dessert to!
