Continuing their guest chef series, Sprig will deliver ICHI Sushi + NI Bar dinners all this week, care of chef Tim Archuleta. Which is great, since this glorious rainfall does not make one want to hoof it out to the Mission. 

Each night, in addition to Sprig's regular dinner options, there will be a custom sushi meal featured which includes a roll plus 4-piece Nigiri.

This week's ICHI Sushi + NI Bar dinners are as follows:

• Tuesday: California Roll and Nigiri: two pieces of tuna, eggplant, inari

• Wednesday: Ocean Trout Roll and Nigiri: albacore tuna, tuna, eggplant, Inari.

• Thursday: Vegetable Roll and Nigiri: tuna, albacore tuna, ocean trout, inari.

• Friday: Tuna Roll and Nigiri: two pieces of ocean trout, eggplant, inari.

There will also be a bump in price point for these prized meals. After all, this is ICHI we're talking about. "Like Sprig, Chef Tim sources only the best ingredients from places like the Tsukiji Market in Japan and sustainably sourced seafood that’s line caught and fresh, organic produce," notes the site. "Given the care that Chef Tim puts into his ingredients and time and effort he's put into creating each dish for his service this week, each sushi dinner will be priced at $17."

You can order via Sprig's iOS app or Android app. Also, their hours have changed—dinner service has been extended from 4 to 10pm.
