Tenjin at Raffles City offers a variety of Japanese tempura dishes praised for their light, crispy batter and fresh ingredients. Despite occasional inconsistencies in food quality and some complaints about service, many diners appreciate the authentic flavors and reasonable prices, especially during promotions. The restaurant features a cozy atmosphere, efficient service, and a strict 45-minute dining limit due to space constraints. While some find the seating arrangements tight and policies rigid, overall, it remains a popular spot for tempura lovers seeking quality Japanese fare in Singapore.
