Soondubu jjigae tofu house cluster in Koreatown

BCD Tofu House originated in Los Angeles’ Koreatown and has expanded into a chain ^[1][2]. Its website and about page confirm its identity as a tofu house but do not describe its broth or tofu style, nor do they name its tofu supplier ^[1][2]. House Foods produces a “Soon Tofu (Extra Soft Tofu)” product specifically marketed for soups and stews, listing ingredients as water, soybeans, magnesium chloride, and glucono delta lactone ^[3]. This confirms that House Foods is a supplier of soon tofu, but the sources do not state which restaurants use it. Beverly Soon Tofu’s website (source ^[4]) contains only a script tag and no usable content, so no information about its broth, tofu style, or supplier can be extracted. No sources mention Pulmuone as a tofu supplier, nor do they provide any details about the growth of the soondubu category from the 1990s to the 2010s.

Summary of what is known: - BCD Tofu House is a chain that started in LA’s Koreatown ^[1][2]. - House Foods sells a soon tofu product suitable for stews ^[3].
