Is this extreme?

I live in San Bernardino and I really want to visit this restaurant I've seen a lot of on social media. I won't give the restaurant's name but I will say that it's walking distance from an A line station. I want to go there but the round trip would be like 3-4 hours if I take the San Bernardino line and then the A line. I've taken Metrolink before but 3-4 hours of travel for one meal feels extreme. I don't know if I should do it.
