Fly Fishing Techniques

I visited Los Angeles last year and went to a restaurant called Asuka located near Wilshire and Westwood Blvd, next to the movie theater. I had a salad which consisted on sliced avocadoes, sliced cucumbers, orange flying fish roe (or tobikko), iceberg lettuce and an off white salad dressing…it was delicious and I want to know what the salad dressing is called and what the ingredients are to make it. Its not very thick, its actually like a watery dressing, not thick like the consistency of caesar dressing. If anyone lives in the 310 area and can call this number of the restaurant and inquire about this salad dressing for me that would be very cool. Im currently in Canada and was seeing if anyone would do this favour for me and post the answer here. Thank you!
