Not sure if you've come down already - but it's def not overkill to eat at all three, you'll just have 3 spectacular meals. Each restaurant is quite different than the other two - so you will have 3 totally different experiences.
Depending on when you come, restaurant week may be going on, which will affect the menu at Husk - so look into that before you go to make sure you're good with it.
You don't need a car unless you plan to go to the beach. Every resto on your shortlist is solid - some are open for lunch and dinner, while others are dinner only. You can squeeze more of your selections in if you plan to have lunch at some of these places - for instance Two Boroughs or Xiao Bao -
enjoy your visit = by the way, i agree with Lynniato's recommendations as well
you'll love the Gin Joint and Pavilion Bar has the money view. The restaurant on the ground floor, Grill 225 has excellent food, and is a value at lunch, you may want to look at that
Gin Joint has great food too.
No Sunday brunch?
agree w previous post about the Taco Spot the owners are lovely people to boot. my favorite fish tacos in chs are at Zia, Coast, and Fuel. I'm not
Fulton Five is romantic but the food at Pane e Vino is better, and the service is excellent. The owner of the place is a very gracious host - Maximilliano.
Also if you like French food La Fouchete is a small restaurant with only about 10 tables and a cozy atmosphere. The owner of that place is Peric, and he and Maximilliano are good friends and former partners in another restaurant. Oak Steakhouse is good but i wouldn't call it romantic. Anson is romantic but very touristy. I've never been to Circa as it pulls from an older demographic.
It really depends on what you are looking for. IF you just want romance, and you want med food like italian or french, you can't go wrong w/ the atmosphere at Fulton Five and the food and hospitality at Pane and La Fouchette.
If you are ok with somewhere more touristy, where you get the old charleston feel, then circa or anson would be better choices.
although technically not in Jerusalem proper just outside of the city is the village of Abu Gosh, where you can find several wonderful restaurants serving authentic israeli salads and grilled meats. One of my favorite places in all of Israel to eat is restaurant Abu Gosh (same name as the village). Caravan restaurant in Abu Gosh is also excellent. Basically the style of food at all of these places is that you sit down and get 6-12 different salads, hummus, tahini, eggplant salads, etc. then you order meats - chicken, kabob, filet, fish, lamb, whatever you want, which come out as a main course. Abu Gosh is famous for their hummus but all of their salads are amazing.
these are not kosher restaurants, although the meat they serve may be kosher.
If you go to restaurant Abu Gosh ask for Alex, who is their head waiter, and you'll get amazing service. Every time I am in Israel i eat here at least twice.
