I've been there at least 6 or 7 times this summer, and sampled a wide variety of entrees, so I'll just give a rundown here:
BEST DISH ON THE MENU AWARD: The Saikyo "King" Salmon. This is just unbelievable, both the presentation (it looks like a work of art) and the taste -- it will literally be the best salmon you've ever tasted, miso-marinated for the better half of a week to give it a delectably sweet accent.
I've brought all manner of people with me, and I've convinced at least 6 or so to try the Saikyo King Salmon -- not one has been disappointed. My friend who actually *hates* salmon with a passion reluctantly gave it a shot, and exclaimed "Whoa, this is really, REALLY good!". It rocks. Try it.
Osso Bucco - If you're in the mood for beef, this is definitely worth trying; very flavorful, especially with the sauce around it. You may also consider the...
Beef Curry - A very mild curry that has a similar taste to the Osso Bucco in a lot of ways. I'm not normally a curry fan, but it made a convert out of me.
Panna Cotta and the Green Tea Blanc Mange are favorites. They're both relatively 'unique', and if you're just trying Cafe Hiro for the first time, they'll be a memorable treat.
If you'd like a little more bang for your buck, the Bread Pudding is really good, though a bit less 'exotic' than the ones above. Either way, you can't go wrong with it.
Appetizers are hit or miss at Cafe Hiro, but the Salmon Spring rolls are delicious. A nice photo of them can be seen here: http://flickr.com/photos/bonnykang/33...
The downside: What you see there is five dollars. Essentially, a single extra-long egg roll sliced into two halves, a tasty appetizer for one person (or two if you're going lite). Still, compared to the rest of the menu (reasonably priced, considering the incredible quality of the food), it seems like you're getting less for your money.
A frequent visitor to Cafe Hiro knows a few things that will make their dining experience that much better.
-It's a different soup every day. All of them are high quality, but if you have a specific favorite, it's best to call ahead and check what the day's choice is (Once you've established a favorite -- mine is their Green Pea).
-Get more out of the salad. Every entree comes with a salad, but the dressing they use is relatively unappetizing. They do, however, make a delicious "Yuzu" citron dressing for some of their other dishes. When ordering a meal that comes with soup and salad, request the Yuzu citron dressing on your salad instead of the normal dressing and you won't regret it.
-The lunch menu eliminates a lot of the great entrees, but you can still have them made up if you ask. The "King" Salmon, especially. If you're taking someone out for a business lunch, requesting for your guest one of the better entrees that's not on the lunch menu is a nice touch.
