At Olhso Korean BBQ & Seafood, a fully robotic kitchen draws attention for both its food and its technology. One customer, San Francisco resident Miles Olson, said he was impressed by what he ordered.
"Galbi, short rib, and it looks really delicious. I've never eaten it before, but it's actually a nice portion," Olson said.
While customers enjoy their meals, operators say soaring diesel costs are creating serious challenges behind the scenes. At Olhso, diesel is essential to power the truck and the robotic cooking equipment.
"Our machine, because it's electric we need to have a really massive, generator," said Edgardo Vicente of Olhso Korean BBQ & Seafood.

Vicente said fuel costs have more than doubled.
"We spent, like, $150 daily. Gas is about $5 grand monthly," he said.
Before diesel prices went up Vicente said, "We were spending around $70, $80 daily."
Just steps away, the Lady M mobile cake boutique is facing similar pressures. Jason Hodges said it costs about $300 to fill up the truck. Two weeks ago, the business invested in an external generator, which he said is already helping.
"It's a luxury cake and we happy to bring it here to San Francisco," Hodges said.
Asked about fuel costs now, Hodges said, "We should probably spend half of what we were spending. So, we are saving money, and we are selling a whole lot more cake. So it's balancing out."
He added, "this generator has an eco-mode, so it'll run this whole trip and burn less gas."
According to AAA, gas prices have increased in all states. The national average price is about $4.55 per gallon for gas and $5.64 for diesel.
"If the straight remains closed. You know, into the month of June, I think by July 4, we'll be at all-time record highs," said Patrick De Haan, head of petroleum analysis at GasBuddy.

Another food truck owner told ABC7 Eyewitness News that it has turned down some locations based on distance and are now being more strategic while waiting for prices to come down.
Olhso recently raised the price of a menu item by a dollar, a move one customer said he understands.
"There's no way that they're going to survive it without increasing their prices. So, for stuff like this I'm very happy to pay a little bit more," said Olson.
Meanwhile, Lady M is gearing up for Mother's Day, with hopes that fuel prices will ease soon.
"We just got to bite the bullet, you know and hopefully just sell more cake," Hodges said.
